Machine-tools; for working any material by removal of material, operated by electro-discharge processes

HS v2017 Code: 845630

About machine-tools; for working any material by removal of material, operated by electro-discharge processes

hs code 845630 covers a specialized category of machine tools used for working materials through electro-discharge processes. These advanced machining techniques are critical for the production of complex, high-precision components across a range of industries, including 848610 Manufacture of engines and turbines, 302100 Manufacture of electronic components and boards, and 251100 Manufacture of structural metal products. The ability to precisely remove material without physical contact makes electro-discharge machining an invaluable tool for modern manufacturing.

Production process

Electro-discharge machining (EDM) is a non-traditional machining process that uses electrical discharges to remove material from a workpiece. The workpiece and a tool electrode are submerged in a dielectric fluid, and a voltage is applied between them. This creates a series of discrete electrical discharges that erode the material, allowing the tool to cut the desired shape. EDM is particularly useful for machining hard, brittle materials and complex geometries that would be difficult or impossible to produce using conventional cutting tools.

Production inputs

The key inputs for the 845630 industry include the workpiece material, the tool electrode, and the dielectric fluid. Common workpiece materials include metals like steel, titanium, and tungsten carbide. The tool electrode is typically made from copper or graphite. The dielectric fluid, usually a hydrocarbon oil or deionized water, serves to insulate the workpiece and tool, flush away debris, and cool the machining area. Additional inputs include the specialized EDM machines, power supplies, and control systems required to precisely regulate the electrical discharges.

Production outputs

The primary output of the 845630 industry is precisely machined components and parts produced through electro-discharge processes. These outputs are then consumed by a wide range of downstream industries, such as 302100 Manufacture of electronic components and boards, 251100 Manufacture of structural metal products, and 302300 Manufacture of communication equipment. The ability to create complex, high-tolerance features makes EDM-machined parts essential for applications requiring tight dimensional control, intricate geometries, and the ability to work with hard or brittle materials.
